This study has much meaning for quickening enterprises’market reaction speed, improving management efficiency and cutting new management practice reference way, but it needs improving indexes quicker reaction speed, and combines special enterprises’characteristics to perfect index system in practices.
at present, industry statistics can' t meet the demand of industry management in our country and many problems exist. We should deepen industry statistics reformation in several below aspects: perfect index system, estab lish modern network of statistics information, increase personnel character, extend statistics influence, change expressing way of information.
Based on result of the theory study of oscillation separation, an oscillating separation cell, the first of its kind, featuring high selectivity, was developed relying on scull-up. The ash of concentrate is reduced by 1.42 % on average while the flotation perfection index improved by 4.14 %, bringing forth therefore a favorable economic result.
Based on single machine check test,small screening test,combustible withdraw rate calculation and flotator complete index calculation,prove that the flotation result is very well.
Under experimental conditions, the ash of theflotation concentrate is reduced by 0.85 percent, with an increase of flotationperfection by 4.34 percent.
On the theory of strategic management accounting, we first propose the industry early-warning index system by literature-reading and perfect it through Delpher inqury.
Regarding basic theories of the green land system and hot environment of residential area as the foundation, green land system of residential area as the research object, hot environment of residential area as the breakthrough point, this text strives to reach expectant targets-"announcing the relation, optimizing the design, perfecting the index" by comprehensive application of the scientific experiment method, systematic analytical method, the comprehensive method and chart-model method.
Taking the database as the core,a more scientific,more authoritarian,multifunctional and integrative evaluation system of scientific and technical articles and periodicals should be built. The paper also makes research on the improvement upon metering index system,document statistical means and computer aided analytic software.
The thermal condition of earth's surface is of great importance to the occur-ence and development of geographic landscape.The scientists took the accumul-ated air temperature(Ta)as main index of belt division in the natural regiona-lzation of our country.becuse the Ta is not a perfect index,we suggest takingthe accumulated temperature of acting surface(Ts)as new index of belt divisi-on in the paper.We discuss the method of determiming Ts from heat balanceequation.The calculations show nhat Ts is a better in...
An evaluation index system has been developed available to get 14 tech-economic indices for evaluating the business management level of metallurgical industries. Two methods of the overall evaluation for business management are described with the system applid to.i. e. the analytic hierarchy process and the comprehensive score. It is important that to play fully the guidance role of the evaluotion index system. metallurgic industries have to streng then the close cooperation with such departments as ban kin...
On the basis of the simple review of “Chinese Scientific and Technical Papers and Citations Database” and other databases,the paper puts forward a proposal that the related department responsible for the work of the Ministry of Science and Technology should act as a mediator to organize the regulation and control.Taking the database as the core,a more scientific,more authoritarian,multifunctional and integrative evaluation system of scientific and technical articles and periodicals should be built.The paper...
